Application filed March 31, 1906. Serial No. 309,202.

7 Gate, of which the following is a specification.

This invention relates to gates, more particularly to the larger-sized farm-gates of the class which may be opened and closed from a distance or by persons from a vehicle or from horseback without alighting, and has for its object to improve and simplify the construction and increase the efiiciency and utility of devices of this character.

With these and other objects in view, which will appear as the nature of the invention is better understood, the invention consists in certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and'in which corresponding parts are denoted by likedesignating characters, is illustrated the preferred form of the embodiment of the invention capable of carrying the same into practical operation.

In the drawings, Figure 1 is a side elevation of the improved gate, partly opened. Fig. 2 is a plan view, enlarged, of the supporting bracket or hanger of the gate detached. Fig. 3 is a view of one of the guiderail-supporting posts, illustrating the manner of coupling the guide-rail thereto. Fig. 4is a sectional detail illustrating more fully the construction of one of the universal joints and the shaft and its casing. Fig. 5 is an end elevation with the carrier-track in transverse section on the line 3 3 of Fig. 1. Fig. 6 is a transverse section, enlarged, on the line 6 6 of Fig. 5. Fig. 7 is a section, enlarged, on the line 7 7 of Fig. 1. Fig. 8 is a sectlonal detail illustrating the coupling means between the guide-rail of the gate and the brace member of the same.

The improved device comprises a plurality of supporting-posts, a guide-track, and a gate for movement transversely of the gatewayopening, and supported upon said-track with means convenient to the hand of a person in an approaching vehicle or upon horseback, whereby the gate may be operated to open and close the same from either side.

The improved device comprises more particularly a relatively large post 10, located at one side of the gatewayopening, which occupies the position of the hinge-post of an ordinary gate, and a latch-post 11, located at the opposite side of the gateway-opening.

Spaced a short distance from the post 10 is a smaller post 12, and spaced at a greater distance from the post 12 is another comparatively small post 13, the two posts 12 13 forming the end supports to a guide-track 14, the latter preferably constructed from a section of relatively heavy piping and secured in any suitable manner in cavities formed in one face of the posts 12 13. Attached to the face of the larger post 10 adjacent to the smaller post 12 is a plate 16, having a supportingsheave 17 mounted rotatively thereon at 18.

The gate is constructed with an upper rail member 19, adapted to bear upon the guidesheave 17, the rail being preferably constructed from a section of piping and the guide-sheave provided with a peripheral groove adapted to receive the rail.

The gate may be constructed of any suitable material, but is preferably formed of piping 20, as shown, and provided with suitable braces 21, the ends of the latter coupled to the end members of the gate-frame by clips 22 23. The clip 23 is extended rearwardly of the gate, as at 24, and curved downwardly and thence bent upon itself, as at 25, and the terminal bent laterally at 26 to bear against the main portion 24and also to form a stop to limit the movement of the gate, as hereinafter explained.

A guide-sheave 27 is pivoted at 28 between the parts of the hanger 24 for bearing upon the guide member 14, while a similar guide sheave 29 is pivoted at 30 between the spaced parts of the hanger 24 for bearing be neath the guide member 14.

The gate is thus supported at one end upon the guiding-sheave 17 and upon the other end by the guide-sheaves 27 29 and the gate thus disposed in positionto be moved transversely of the gateway-opening. The bend 25 extends beyond the sheave 29 and shields the same and protects it from contact with the post or standard 13 when the gate is moved into extreme open position, while the lateral projection 26 at the other end serves the same purpose for the other sheave 27 when the gate is in closed position.

The post 10 is provided with a transverse aperture 31 just above the point where the sheave 17 is located and the plate 16pmvided with inwardly-extending flanges 32 33 and bearing within the aperture 31.

A shaft 34 is disposed through the aperture 31 and extends at both ends beyond the post 10 with the terminals squared, as at 35 36, to receive the rotating mechanism, as hereinafter explained. The shaft is sup ported near one end by a bearing 37 and near the other end by a bearing 38, disposed with l in the aperture 31 and between the bearingfianges 32 33 of the plate 16. The shaft 34 is provided exteriorly of the plate 1.6 with a relatively large operating-sheave 39, bearing upon the upper side of the rail 19 and above the supporting-sheave 17. Gears 90 91 are connected, respectively, to the shaft 34 and guide-sheave 17, so that the latter is positively driven from the shaft 34 to increase the efidciency of the device and also provide means whereby accumulations of ice or snow are prevented from obstructing the parts or interfering with their operation. Bearing upon the shaft 34, between the flanges 32 33, is a block 40, having a pin 41 for supporting the lower end of a spring 42, the upper end of the spring bearing against the body of the post and within a socket 43, formed for the spring in the post. By these means the shaft is yieldably supported in position, so that the bearing-sheave 39 also bears yieldably upon the rail member 19. The plate 16 is provided with spaced guides 44 45, between which a closure-plate 46 is disposed and adapted to cover the socket 43 and spring 42, disposed therein. By this means it-will be obvious that when the operating-sheave 39 is rotated in one direction the friction of the sheave operating upon the rail 19 will move the gate in one direction over the guide-sheave 17 and along the guide-track 14, and when the motion of the operating-sheave is reversedthe gate will be moved in the opposite direction.

The means employed for operating the sheave 39 consists in two shafts, indicated, respectively, at 47 48, with universal joints 49 50 at the inner ends, having sockets adapted to engage the squared ends 35 36 of the shaft 34, the shafts 47 48 extended laterally to a sufficient distance and provided with operating-cranks 51 52, the shafts 47 48 being long enough to bring the cranks within reach of a person in a vehicle or on horseback, as above noted. The shaft 47 is inclosed in a tubular casing 53, and the shaft 48 is inclosed in a tubular casing 54, the tubular casing 53 having a sleeve 55 slidable thereon and the tubular casing 54 having a sleeve 56 slidably disposed thereon.

Pivoted at 57 to the sleeve 55 is a brace 58, and pivoted at 59 to the sleeve 56 is a brace 60, the two braces 58 and 60 being pivoted at 61 62 to straps (one of which is represented at 63) upon the post 10 at or near its upper end. The braces 58 and 60 are preferably arranged in pairs and'diverging from the outer pivot-points 57 59 to the straps 63, connected to the opposite sides of the post 10.

Connected to the upper end of the post 10 i is abase member 87, supporting a standard 62, preferably of a section of piping, the standard having a bracket 88 at its upper end and carrying a shaft 64. Rigidly supported upon the shaft 64 is a drum 65, provided with a l ratchet-wheel 66, a pawl 67 pivoted upon the bracket 63 engaging the ratchet-wheel and preventing backward movement thereto. The shaft 64 is provided with an operatingcrank 89.

Winding-cables 68 69 are connected at one end to opposite sides of the drum and with their other ends connected, respectively, to the tubular casings 53 54 near the outer ends obvious that when the shaft 64 is rotated by its crank 89 the drum rotating with the shaft will wind the cables thereon and elevate the outer ends of the tubular casings 53 54, to

and thus dispose the operating-cranks 51 52 at any desired distance from the ground, the pawl67 holding the drum and the cables at any required adjusted position.

As the vertical adjustments are made by the rotation of the drum the sleeves 55 56 will slide upon the tubular casings 53 54, while the braces 58 60 will swing upon the pivots 61 62, and thus avoid cramping any of the parts. As the cranks 51 or 52 are actuated. and the yieldable operating-sheave 39 thereby caused to rotate over the gate-rail 19 and the gate moved thereby, any slight irregularity in the construction will be automatically compensated for by the yieldableness of the sheave 39 and its supporting mechanism.

Pivoted at 70 to the frame of the gate is a latch 71, having a recess 72, adapted to bear over a keeper 73 upon the latch-post 11 when the gate is closed, and thus automatically lock the gate in closed position.

Pivoted at 74 to the framework of the gate is a latch-lever 75, the latter pivoted at 76 to the inner end of the latch 71 and with its rear end extending beyond the rear member of the gate and bent laterally, as at 77.

Pivoted at 78 to the post 10 is a trip-shaft 79, extended at one end, as at 80, into the ath of the laterally-bent terminal 77 of the ever and with the other end extended at 81 and terminating in an eye 82 to receive pull-cords 83 84, leading thence through guiding-eyes located at some point near the operating-v handles 51 52, preferably as at 85 86 on the sleeves 55 56. 5

The portion of the trip-shaft 79 extends beneath and in close proximity to the laterally-bent portion 77 of the lever 75 when the gate is closed, so that the latch 71 may be readily released by pulling downward upon either one of the pull-cords depending from the guiding-eyes 86. By this arrangement when a person approaches the gate he of the latter. By this arrangement it will be gether with the shafts supported thereby,

ICC

first draws downward upon the nearest pullcord to release the latch 71 and then rotates the nearest handle 51 or 52, as the case may be, in one direction, and thereby causes theopening of the gate. After passing through the gate the driver or rider rotates the other handle'5l or 52, as the case may be, to close the gate, the latch mechanism requiring no attention when closing the gate, as it operates automatically under stances.

When the gate is closed, the offset 26 engages the standard 12, and thus limits the movement in that direction and obviates undue friction against the latch-post;

The brace 21 is spaced away from the rail 19 at the point where it is connected thereto, so that the connecting means between the brace and rail passes between the sheaves 17 and 39, as will be obvious, the construction of the coupling means between the brace and rail being illustrated more fully in Fig. 8.

All the parts may be of metal or'partly of metal and partly of Wood, as may be pre-v ferred but preferably all the parts will be of metal except the posts.
